Watch: Ylvis performs ‘The Fox’ for a costumed Jimmy Fallon

Lucky you: your all-time favorite band went on “Late Night with Jimmy Fallon” to perform your all-time favorite song! Yes, of course I’m talking about Ylvis and “The Fox.” What, are you some kind of Beatles fan or something?

Also? Apparently their name is pronounced “Ill-vis” and not “Yill-vis,” so be sure to chastise all your friends who say it the wrong way.
